DUMP-WAGON.

Specification of Letters Patent.

Patented May 305, 1916.

Application filed November 18, 1915. Serial No. 62,131.

To all whom it may concern:

Be it known that I, HERMAN MECKING, a subject of the Emperor of Germany,and a resident of the city of New York, borough of Bronx, in the countyof Bronx and State of New York, have invented a new and ImprovedDump-Wagon, of which the following is a full, clear, and exactdescription.

My invention relates to dump wagons and has reference more particularlyto the dumping end thereof.

An object of the invention is to provide a simple, strong andinexpensive dumping wagon which will not allow any liquid matter presentin the wagon to leak out.

A further object of the invention is to provide a dumping wagon operablefrom the front end of the wagon and in which the engagement of thedumping trap with the rear end of the wagon is rendered noiseless.

With the above and other objects in view, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combination and arrangement of parts as herein fullydescribed, illustrated and claimed.

In the accompanying drawings, forming part of the application, similarcharacters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of my wagon, the rear end of which ispartially in section to show the details of construction; Fig. 2 is aside elevation of the wagon in the dumping position; Fig. 3 is a framentary side elevation of the rear end of the wagon partly in section toshow the details of construction; Fig. 4 is a fragmentary section online 4-4, Fig. 3; and Fig. 5 is a perspective elevation of the bodylocked at the front end of the wagon.

Referring to the drawings, 6 represents the body of the wagon, which ispreferably made of sheet iron. The bottom. 7 of the wagon slopes fromthe ends toward the middle thereof, and the rear end slopes toward thebottom, so that the length of the body is greater near the bottom, whilethe width of the wagon is substantially uniform. The top of the body isclosed, and a suitable door 8 is provided through which the wagon bodyis charged. Trunnions 9 are provided on the sides of the wagon body inthe central part thereof adjacent the bottom of the body, the trunnionsbeing carried by bearings 10 provided on the longitudinal frame members11 of the wagon. In view of the fact that the bottom of the wagon slopestoward the central part thereof the front and rear ends in the normalposition of the body, as shown in Fig. 1, are above the trunnions 9.

The rear end of the body is normally closed by a trap formed of twosections 12 and 13. Section. 12, is hinged to the body at the topthereof, and section 13 is secured at its lower end to the ends of thelongitudinal frame members 11. Section 13 has an inwardly directedflange 14 at the top thereof normally overlapping a flange 15 of thesection 12 directed outwardly. The section 13 has also an inwardlydirected flange 16 adjacent the bottom edge thereof and adapted to comein contact with the bottom 7 when the flang 15 comes in contact with theflange 1.4 of the section 13. The side edges of the section 13 haveinwardly directed flanges 17 adapted to engage the sides of the body andat the ends of which flanges laterally, outwardly directed flanges 18are formed. The flanges 18 are preferably connected by a brace orreinforcing member 19,

forming an integral part of the flanges 17 and 18, to the adjacent endof the longitudinal frame member 11. The flanges 18 are preferably in aplane parallel to the plane of the section 13. Secured to each of saidflanges 18 is a gasket 20 preferably formed of a leather strap. Alateral flange 21 is provided on each side of the body adjacent the rearsloping edge for engaging the gasket carried by the flange 18 when thebody is in normal position, as shown in Figs. 1, 3 and 4. By forming thejoint between the section 13 and the body beyond the sloping edge of thesides of the body the flow to the joint is broken and, therefore, thepossibility of leakage is reduced. It will be noted that the engagementof the flanges 14 and 15 of the sections 12 and 13 brings the section 12into engagement with the sloping edges of the sides of the body.

To prevent an accidental displacement of the body on its trunnions, atongue 22 is provided at the front of the body adjacent the bottomthereof which is normally engaged by a lever 23 pivotally mounted atoneend thereof in a swivel 24 which is in turn secured to a transversemember 25 extending between the longitudinal frame members 11. A bracket26, also mounted on said transverse member, is adapted to receive thelever. Locking means 27 are provided in said bracket for retainingthe'lever, whereby the tongue is locked to the transverse member. Whenthe body is to be dumped thelocking means 27 are removed from thebracket, thus the lever 23 can be swung out of the bracket and to oneside thereof, so as to permit a free movement to the tongue when thebody is moved on its trunnio-ns to the dumping position. It will benoted that as the body moves on its trunnions the section 12participates in the movements of the body, while section 13 isundisturbed. The flange 15 is so designed that it will pass clear of theflange 16 in the downward movement of the body. The inclination of theflanges 18 is also such that the flange 21 can move freely. Due to thefact that the bottom 7 at the rear of the wagon is normally above thetrunnions 9, the body 6 has a larger angular swinging movement on itstrunnions than it would have if the bottom thereof was not sloping ashas been described. Furthermore, the sloping bottom causes anaccumulation of liquid, that may be present in the matter in the body,in the lower part of the bottom; thereby chances for leakage at theraised discharging end of the bottom is substantially eliminated.

To prevent any relative displacement between the body 6 and the trapsection 1.3 the f sins of the wagon is suspended on an axle 28 byeiliptical springs 29 which are interposed between the longitudinalframe members 11 and the axle, In view of the fact that the body islocked to the frame by the lever 23 it will participate in all themovements of the frame during transit, and, therefore, no relativedisplacement between the body and the trap section 13 can take place.After the wagon body has been dun'iped and is moved to its normalposition, the engagement of the body with the stationary section of thetrap is rendered noiseless by the provision of the leather straps on theflanges 18 which constitute the gaskets preventing leakage.
